A F Out Put Power Meter

A F Out Put Power Meter:

PACIFIC’S PAF - 30 measures A.F. signal power from - 20 dbm to +45dbm and 0.01 mw to 30w max,.
frequency range includes 20Hz to 30 KHz.

TECHNICAL DATA:

Frequency Modulation and Demodulation (Model: AC-02)

Objectives:

To study how the modulating signal changes frequency of the carrier rather than amplitude and observe the frequency modulated waveform.

To observe the changes in carrier centre frequency and to observe the frequency deviation, and to observe how the phase lock loop can be used for FM demodulation.

Specifications:
This unit consists a built in power supplies of +12V,-12V@300mA Along with Carrier generator using 8038 IC with fixed frequency 50KHZ and fixed amplitude. And the direct method is used for modulation circuit with RC combination.

And also phase lock loop 565 IC and Op-amp 741IC is used in demodulator circuit.

Set of 2mm patch cards and user manual is accompanied with this kit.
Optional items required:

Dual trace CRO DC-30MHZ.
